CRL Zipper Pile Weatherstrip 100' Roll, 0.4" Pile, .187" Backing

• Replaces old or worn-out pile weatherstripping in doors and windows
• Zipper tooth design snaps pile into extrusion slots from above for faster installation
• High-density gray pile with double center fin for a true weather seal

CRL Zipper Pile Weatherstrip (SKU Z78238C) is a full-density, water-resistant pile woven to a unique zipper-tooth polypropylene backing. The zipper-tooth design lets the pile snap into T-slots from above instead of sliding in from the ends, making retrofit installation into aluminum, vinyl, fiberglass, or wood T-slots faster and easier—even if the slot is slightly off size. Use this zipper pile weatherstrip for doors and windows where a durable, high-performance seal is required. The double center fin offers superior weather sealing compared to piles without a fin, reducing vibration, drafts, water intrusion, and pest entry.
